Hey ππ»,
every time I buy something with my card, I take a picture of the receipt to attach it to the transaction in the bunq app, so that I always have a receipt to either get something returned or replaced. But I don't really like, that it just takes a normal image. That's why I would suggest implementing a scanner which automatically crops the image to the right receipt size and also makes it black and white. From now on I use Adobe Scan but it would be great to have something similar to Adobe Scan, etc. in the bunq app.
